EWI supports the manufacturing industry through the development and incorporation of testing, assessment and prevention technology for cracking and damage of structures. Our team, with more than 75 years of combined experience, specializes in fracture, fatigue, and time-based degradation of metal properties. We focus primarily on welded structures, using EWI’s extensive welding, forming and metallographic capability on-site for assessments. Beyond failure assessment, we are able to use the approach of preventing cracks as a central basis of designing larger systems, where crack-related failure modes are particularly troublesome.

Featured Engineer

For over 20 years at EWI, Bill Mohr has offered expertise in fitness-for-service assessment, design, and fatigue of welded structures for member companies. Bill has worked on projects examining different weld processes to determine if welding process variables can be changed to improve fatigue performance, fitness-for-service analyses involving refinery components, and more. He has also led numerous projects involving tests of metal components for strength, toughness, fatigue resistance, and fatigue threshold. Bill holds degrees from MIT and Stanford.
